INTRODUCTION AND CONTENTS

Congratulations on choosing Australian Monitor for your professional ampliﬁcation requirements.

The design of our HSP series constant voltage power ampliﬁers embraces all the aspects of a well-designed ampliﬁer. The visual design, mechanical, electrical and sonic parameters, along with our dedicated manufacturing process, have all been optimised to provide a professional tool that exhibits quality, reliability and longevity.

The HSP series ampliﬁers are 1 unit 1.75” high, 19” wide, or 2 unit

3.5” high, 19” wide rack mountable units depending on the model.

Models are available in 1, 2 and 4 channel versions. The HSP ampliﬁer is fully controllable over the included USB and RS232 interface which provides conﬁguration and monitoring capabilities. An included mini DSP also allows control of the volume, muting, compressor/limiter and input channel selection which feeds an efﬁcient Class D ampliﬁer to deliver 120W or 250W of output power per channel.

These ampliﬁers have been speciﬁcally designed to deliver their high power output with minimal distortion, and provide the critical degree of control required by your speakers.

CONTROLS, CONNECTORS & INDICATORS

FRONT PANEL

HSP 1 Channel 1RU shown in above example.

USB Communications Port

Plug in the supplied USB Type A to Mini Type B connector into this port to communicate with the ampliﬁer from the PC software application. The PC software application, downloadable from the Australian Monitor website, allows for real time monitoring of the ampliﬁer inputs and outputs. The PC software application is also used to conﬁgure the DSP functionality to cater for the installation environment.

Consult the Software Control Over USB setup section of this manual for further details of this control.

LED Indicators

Status Indicator

This blue LED indicates various states of the ampliﬁer.

LED MEANING INDICATION

Blue On Normal Operation LED solid on. Indicates that device is powered and that no faults exist.

Blue Slow Flash Standby Mode Flash LED: On for 50ms, Off for 4s

Blue Flash Error Mode LED Off for 2s followed by a ﬂash count of the error code, On for 300ms, Off for 300ms. Multiple errors will be indicated in

consecutive error sequences. Refer to the Fault Finding section of this manual to ﬁx any errors displayed.

See the Fault Finding section of this manual to ﬁx any errors displayed.

Protect Indicator

The following table indicates the meaning of each protection mode:

LED Meaning

Yellow ﬂashing Ampliﬁer temperature warm

Yellow on Ampliﬁer temperature hot

Red ﬂashing Ampliﬁer over temperature*

Red on Ampliﬁer protect

See the Fault Finding section of this manual to ﬁx any errors displayed.

* In the advent of a thermal overload, the internal operating temperature

of the ampliﬁer has exceeded a safe level of operation. The fan will continue to run and once the ampliﬁer has cooled it will return to normal operation.

Signal LED

The following table indicates the meaning of the signal LED

LED Meaning

Green ﬂashing Audio signal mute

Green on Audio signal present

Output Clip indicator

A red LED will illuminate when output signal clipping occurs.

Power Switch

Press the switch to the up position to power the unit on. At start-up (turn-on), the input to the ampliﬁer is muted for approximately two seconds.

REAR PANEL

Mains Input Connector

Your ampliﬁer is ﬁtted with a standard IEC 60320-C14 socket for mains connection. Use the mains cable supplied to power up the unit.

NOTE: Your unit must always be earthed!

Speaker Outputs

The class D ampliﬁer output features 100V Line, 70V Line or 4 Ohm low impedance operation.

IMPORTANT: Remove the speaker connector link if operating the ampliﬁer

in 4 Ohm operation.

NOTE: Only one output type should be used at a time.

RS232 Communications Port

The RS232 port is designed to be connected to an external control system or to a remote PC. Using an RS232 converter (not supplied), connect to this port to communicate with the ampliﬁer from the PC software application or via serial commands. The PC software application allows for real time monitoring and conﬁguration of the ampliﬁer.

Consult the Software Control Over RS232 setup section of this manual for further details of this control.

External Mute, Standby and Fault

External Mute

Connect this input to ground (GND) to mute ampliﬁer channels.

Consult the External Mute section of this manual for further detail of this control.

Standby

Connect this input to ground (GND) to enable standby mode.

Consult the Standby Input section of this manual for further detail of this control.

Fault

This active low output indicates a fault in the ampliﬁer. There are two possible faults that can be indicated:

•

The ampliﬁer has gone into thermal shutdown due to a measured high temperature

•

The ampliﬁer has detected an overload condition on the speaker terminals

Consult the Fault section of this manual for further detail of this control.

Input Channel Clip LEDs

The input channel clip LEDs are used to indicate that the input signal is being clipped. If the input is clipping, reduce the signal by turning the attenuation pot counter-clockwise (when viewed from rear) until the clip LED ever so slightly turns on with an input source present.

The input source should be representative of the audio that will be used in the system on a daily basis.

CONTROLS, CONNECTORS & INDICATORS

Input Signal Attenuation Pot

The fully clockwise position (when viewed from rear) of the input signal attenuation pot provides no attenuation (ie 0 dB). Turning the pot counter clockwise provides a logarithmic attenuation all the way to -128 dB.

Phoenix Balanced Input

A balanced male 3-pin (3.81mm) Phoenix type connector is provided on each input channel.

Consult the Balanced Input Wiring section of this manual for further detail of this control.

Ground Lift

Use the DIP switches to control the grounding of the audio inputs. The switch for the given channel is pushed down to connect the input signal ground with the mains safety ground. The piano DIP switch is in the lift position (ie up) when the input ground needs to lifted from the mains safety ground to prevent circulating earth loops.

If at anytime a hum or unwanted noise is experienced then the input should be conﬁgured so that the input signal ground is lifted from the mains safety earth. This minimises the circulating ground loop current by adding in an impedance which results in signiﬁcantly less loop voltage drop being ampliﬁed by the ampliﬁer.

SOFTWARE SETUP (CONT)

RS232 using the PC application

Most modern PC’s require a USB to RS232 converter for RS232 operation.

A suggested RS232 to USB converter is the FTDI (USB-RS232-WE-1800BT_5.0) which can be sourced through most online electronic component stores.

Wire up the USB to RS232 converter like the image at left [see page 8]

using the supplied green 3-way Phoenix connector. Note it’s important that the RXD and TXD of the HSP pins must join to the TXD and RXD of the converter respectively.

Turn on the power to the HSP unit by pushing the front panel switch up.

Plug in the supplied RS232 cable to the rear of the HSP unit and USB port

to the PC.

Make sure the driver for the RS232 to USB converter cable has installed

correctly. This can be checked by opening windows device manager. To do this select (Start -> System -> Device Manager) and then make sure there are no devices marked as inactive due to a missing driver.

Double click on the installed application HSP Control Software VX.X.X.

Select the USB to RS232 converter manufacturer from the dropdown

menu. Note: if using the FTDI cable that is suggested above it will display as (USB Serial Port (COMXX)) where COMXX will display the COM port number chosen by the PC. See image below:

Upon successful connection the main application window will look like the

image below (Note: The number of channels displayed will depend on the HSP model):

RS232 using an external control system

Connect the external control system to the RS232 port of the ampliﬁer.

Conﬁgure the RS232 port settings as per the setup information above

Referring to the serial command section, send and receive commands

using the external control system.

Example command to enter standby:
